Wacker Neuson 5100011820 Spacer Ring

The Wacker Neuson Spacer Ring is a genuine OEM component designed for the RD18, RD24, RD27, RD28, RD40, and RD45 series tandem rollers. Sourced directly from Wacker Neuson, this spacer ring meets the exact dimensional and material standards of the original part. It provides a direct, drop-in replacement across a wide range of tandem roller configurations including standard, combination, offset, DPF, and electric variants. Whether you are servicing a single machine or maintaining a fleet, part number ensures your repair is completed with a component built to the same specification as the one it replaces.

Key Features

• Exact Dimensional Tolerance — Manufactured to OEM specifications, this spacer ring maintains the precise axial clearance and load distribution required for correct drum and drivetrain alignment.
• Direct Drop-In Replacement — Installs in the same position as the original, with no rework or modification to mating components needed for fitment.
• Broad Tandem Roller Compatibility — Fits RD18, RD24, RD27, RD28, RD40, and RD45 series tandem rollers across standard, C, O, DPF, US, SE, and electric (e) configurations.
• Protects Adjacent Components — A correctly fitted spacer ring prevents metal-to-metal contact between rotating assemblies, reducing wear on bearings, shafts, and housings over time.
• Genuine Wacker Neuson OEM Part — Supplied as an authorized OEM replacement, ensuring this part matches the original in material grade, hardness, and geometry.

A spacer ring is a precision-machined component used to establish and maintain correct spacing between rotating or sliding parts within an assembly — most commonly between bearings, shafts, drums, or housings. On a tandem roller, it ensures that drivetrain and drum components are held at the correct axial position, preventing side load, vibration-induced migration, and premature wear on surrounding parts. When a spacer ring becomes worn, corroded, or dimensionally out of spec, it can allow unwanted movement in the assembly, leading to accelerated bearing failure, unusual vibration, or misalignment that affects compaction performance and machine longevity.
